The Mountebank

Hat Man is an Animi Avatar playable character in the Multiplayer component of Assassin's Creed III. He wears a thick, black coat that hides most of his clothing's details, and a top hat and sunglasses adorn his bearded head. His gloved hands wield a kitchen knife.

His real name was Victor Wolcott, a vile and dangerous doctor who became infamous for his schemes and lies. The word Mountebank is a word derived from Italian which translates to the fraudulent practice of selling dubious medicines on a stage, or in basic terms "Charlatan" or "Quack".
